We write to inform
you that Vringo Infrastructure, Inc. ("Vringo"), a subsidiary of Vringo, Inc., has acquired a portfolio of patents
and patent applications, a number of which are considered essential to infrastructure equipment and mobile stations compliant with
Global System for Mobile Communications/General Packet Radio Service ("GSM/GPRS") specifications as defined by
the European Telecommunications Standards Institute ("ETSI") and/or the 3rd Generation Partnership Project ("3GPP"),
and the Universal Mobile Telecommunications System Standard ("UMTS") as promulgated by 3GPP and/or ETSI. Declarations
have been filed related to patents from thirty-one families, indicating that those patents are or could become essential to relevant
standards. The portfolio also includes a number of patents which are not currently considered essential to such standards, but
which may nevertheless be infringed by certain infrastructure equipment and mobile stations. Vringo has also acquired the right
to recover damages for all past infringement related to the portfolio.

We understand that
ZTE Corporation and its subsidiaries (together, "ZTE") do not have a license under any of the patents in the portfolio.
We further understand that ZTE has been manufacturing and selling UMTS and/or GSM/GPRS equipment since at least 2002. Clearly,
ZTE has had a very long period of time to evaluate and consider patents in the portfolio, and has evidently decided not to take
a license to them. We recognize that ZTE is familiar with the ETSI Intellectual Property Rights ("IPR") database
and its predecessor systems, on which declarations can be conveniently accessed. Indeed, ZTE itself is listed as having declarations
with respect to a large number of patents on that system.

We invite ZTE to consider
again whether any license to the patents is required. If ZTE determines that a license is required, we invite ZTE to make a concrete
request for such license, identifying the patents to which ZTE would wish to take a license, and the consideration proposed by
ZTE.

Vringo is prepared
to license all patents which are Essential (as that term is defined in the ETSI IPR Policy) to a standard, provided that the consideration
proposed is fair, reasonable and non-discriminatory ("FRAND").

If and for as long
as ZTE does not make a concrete, binding offer to take a license capable of acceptance by Vringo, which would include a FRAND payment
for all past infringement, and which would result in a license to Essential patents on FRAND terms, Vringo will pursue all legal
remedies available.

A list of acquired
patents as can be found in Vringo Inc.'s filing with the United States Securities and Exchange Commission on Form 8-K dated August
9, 2012 at Exhibit 99.1. The list may be supplemented in the future if there are any required additions, deletions or modifications.

We look forward to
your response. Please address all correspondence to the undersigned.
